**Question:**What mass of rubidium chloride can be produced directly from 8.36 g of rubidium and 8.36 g of chlorine?**Chemical Reaction:**\[ 2 \text{Rb} + \text{Cl}_2 \rightarrow 2 \text{RbCl} \]**Your Answer:**- [Answer Input Box]- [Units Input Box]**Explanation:**The question involves a stoichiometric calculation based on the balanced chemical equation. It asks for the mass of rubidium chloride (RbCl) that can be formed from given quantities of rubidium (Rb) and chlorine (Cl₂). Input your answer in the provided boxes, specifying both the numerical value and the units.

Mass of Rubidium chloride formed can be calculated from limiting reagent.Answer: 11.7468 g Explanation: Given balanced reaction for Rubidium chloride formation is: 2 Rb + Cl2 → 2 RbCl Given mass of Rb = 8.36 g => moles of Rb = mass ÷ molar mass = 8.36 g ÷ 85.4678 g/mol = 0.0978 mol => moles to stoichiometric coefficient ratio for Rb = moles ÷ stoichiometric coefficient = 0.0978 mol ÷ 2 = 0.0489 mol Similarly for Cl2: Given mass of Cl2 = 8.36 g => moles of Cl2 = mass ÷ molar mass = 8.36 g ÷ 70.906 g/mol = 0.1179 mol => moles to stoichiometric coefficient ratio for Cl2 = moles ÷ stoichiometric coefficient = 0.1179 mol ÷ 2 = 0.1179 mol Since moles to stoichiometric coefficient ratio is least for Rb so Rb will be the limiting reagent and will completely consume and will decide the mass of Rubidium chloride produced. Two mol of Rb produce, moles of RbCl = 2 mol => 0.0978 moles will produce = 2 × 0.0978 mol ÷ 2 = 0.0978 mol of RbCl Since mass of RbCl produced = moles × molar mass => mass of RbCl produced = 0.0978 mol × 120.921 g/mol = 11.7468 g So mass of Rubidium chloride produced is 11.7468 g
